ting out labels or the like from successivef portions of a web or stripof paper, and particularly gummed paper.

Another object is to provide an improved form of punching mechanismwherein the punch and die are both advanced fora certain distance andthereupon the die is arrested while the further advance of the punchwill cause the label to be severed.

In the accompanying drawings showing one embodiment of my invention,Figure l is a vertical sect-ion on the line 11, Fig. 3; Fig. 2 is a sideelevation; Fig. 3 is a plan view; Fig. 4 is a vertical section on theline 44 of Fig. 3; Fig. 5 is a-vertical section on the line 5-5 of Fig.3; Fig. 6 is a view similar to Fig. l "with the parts in the openposition; Fig. 7 is a section on the line 7-7 of Fig. 3; Fig. 8 is aside elevation, and Fig.'

9 a bottom plan view of the die member and its support; Fig. 10 is aside elevation; and,

Fig. 11 a bottom plan of the stripper member for the die.

The machine isshown as comprising a suitable base 12, provided withstandards 13 and 14 forming bearing members for a beam 15 pivotedbetween these standards at one end by a shaft 16.

At the front portion .of the maclnne a crank shaft 17 is mounted inbearing members 18 and 19 extending up from the frame,

which shaft is shown as driven by a pulley 20. The crank portion 21 ofthe shaft has a sleeve 22 rotating in a split block 23 that will becaused to travel in a circular path. This block slides in a slot 24 inthe beam 15, as indicated in Fig. 1, and therefore the movement of theblock will cause oscillation of the beam 15 according to the verticaltravel ofthe block. A guide-block 25 is shown as slidable by its ends inguide-ways 26 and 27 in the side members of the frame,

and carries a punch 28. The punch block is normally retained in itsupper and .open position by a bent lever 29 whose arm engages the blockto move it upward, the lower arm of the lever being connected witha coilspring 30, whose other end is secured to a lug 31 on'the frame. Tomovethe punch downward, it is engaged by a block 32 secured on the beam .15that will engage the punch block 25 at the lower portion of the strokeand move the punch downwardly; and on the return stroke of the beam thespring 30 will cause the lever to raise the punch and block and hold itagainst a suitable stop pin 33 on the frame. The arrangement of the dieto cooperate with this punch consists of a resilient arm 34 that issecured to a bar 35, which latter is secured to the punch block 25. Thedie 34 has an opening at 36 to receive the punch 28. The resilient punchplate 34 has its movable end 37 provided with a slot 38 through whichextends a screw 39 secured in the plate 35, the head of the screwserving to limit the downward swing of the die plate, as indicated inFig. 8. In this position the die plate is a short distance removed belowthe end of the punch, and the web is passed across the die plate underthe punch. A guide on the stripper plate is provided in the form of aplate 40 having an opening 41' to receive the punch, and havingoverhanging lugs 41 at each corner of the plate that engage the sideedges of the die plate 34, as indicated in Fig. 6. The stripper plate40, of course, is offset from the die plate a short distance to permitfree movement of the web, and as the punch recedes it will strip theapertured web from the punch, and will also serve to prevent the webfrom curling up as is usual with gummed paper. To cause the punch toenter the die a suitable obstruction, such as a bolt 42,projectsupwardly through the base 12 to engage the die plate beyond thedie and stripper plate, as indicated in Figs. 6 and 8. At the latterpart of the downward movement of the punch, this bolt will strike thedie plate and arrest its movement, whe-re-' upon the punch will passthrough the hole in the die plate and cuta label from the web WV. Meansare also provided for advancing the web through the impression de-Patented Mar. 4, 1913.

vice and through the punch device; and such means are arranged toprovide slack in the web as it is advanced. At the front of'the machineare mounted a air of horizontal rolls 66 and 67. A gear 0 engages a rackbar 71 pivoted to the arm 58. The oscillation ofthis' arm willreciprocate the rack bar and swing the gear 70. A pawl 72 on this gearengages a ratchet wheel 73 fast on the shaft 74 of the lower roll,whereby these rolls are intermittently advanced from the movement of thebent arm- 58.

At the rear of the machine are arranged a pair of rolls 7 5 and 76between which the web isadvanced by their rotation, one of the rollshaving a shaft '7 7 carrying a ratchet wheel 78. An arm 79 on the shaft77 carries a awl 80 that when the arm is swung, will a Vance the ratchetwheel and hence the rolls will be swung forward a short distance.

A very'simple form of punch and die is arranged in which the die memberis carried by the punch and at the end of its operating movement the dieis arrested causing the punch to pass through the die aperture and severthe label.

Having thus described my invention, I claim:

In a device of the character described, the. combination of a frame,a beam pivotally mounted on the frame, means for oscillating thebeam, apunching device comprising a block slidable in, the frame to bereciprocated from the movement of the beam, a punch fast on said block,a cooperating die member movably carried by the block, and a stop memberon the frame arranged to engage the die member as the block is broughtdown by the beam to cause the punch to enter the die member.
